Noctua NF-A14x25 G2 PWM Sx2-PP is a package that includes two NF-A14x25 G2 PWM fans. This powerful duo is specifically designed for push-pull cooling solutions and situations where two fans operate side by side, such as case cooling or 280 mm water coolers. The speed difference between the fans minimizes unwanted noise and vibrations.

When two fans run at nearly the same speed in a push-pull configuration or side by side, their acoustic interaction can cause disturbing sounds like vibrations or humming. The speeds of the fans in the NF-A14x25 G2 PWM Sx2-PP package are finely tuned with about a 25 rpm difference, effectively preventing such phenomena. This enables efficient cooling without disturbing noise.
